“…It is also a factor that helps in increasing and maintaining the carbon content in an area. Decreasing vegetation density can cause a 56% decrease in the amount of carbon (Pandey et al 2020;Purnomo et al 2022). This is in line with a previous study that its reduction in lowland land areas led to a loss of 269.1-46.3 MgCha -1 (Astiani et al 2017).…”

Abstract. Marimpan LS, Purwanto RH, Wardhana W, Sumardi. 2022. Carbon storage potential of Eucalyptus urophylla at several density levels and forest management types in dry land ecosystems. Biodiversitas 23: 2830-2837. Tropical forests can store high amounts of carbon because they have suitable environmental factors. Furthermore, they are different from others that grow in dry areas, which tend to experience limited rainfall. Ampupu (Eucalyptus urophylla) is an endemic tree in East Nusa Tenggara, which is continuously damaged. This is caused by various anthropogenic activities, which increase along with the population around the forest. Therefore, this study aims to estimate the carbon content stored in natural forest areas of E. urophylla at different density levels and land use types. Field inventory was carried out in the study location using the stratified sampling method, after which the density levels were divided into three groups, viz. high, medium, and low. Sampling was then carried out in 3 different land-use areas, including production, protection, and conservation forests. Furthermore, a total of 90 plots were used, where each land-use type consists of 30 plots with a size of 25 m × 40 m. The results showed that the carbon content at the low, medium and high-density levels were 108.20, 185.24, and 291.33 MgCha-1, respectively. Values of 211.91, 214.69, and 221.14 MgCha-1 were also obtained from the production, protection, and conservation forests, respectively. Based on the results, the natural forests of E. urophylla have a significant effect on carbon sequestration in East Nusa Tenggara.

“…Terminalia bellirica has been reported to have high carbon sequestration in India (Aggarwal & Chauhan 2014;Dhyani et al 2021). It also has aboveaverage carbon sequestration capacities among naturally growth vegetation in a mining recovery project in Indonesia (Purnomo et al 2022).…”

“…Cananga odorata is the dominant tree species in the Tangkoko Natural Reserve, Indonesia, where it responsible for a high biomass contribution (Langi 2023). The species has the highest carbon sequestration capacity among naturally growing vegetation in a mining recovery project in Indonesia (Purnomo et al 2022). Surprisingly, A. marginata has better growth than C. elastica, even though its diameter and height are less.…”

The use of native trees is necessary for land restoration and the sequestration of carbon that is stored in forest biomass production in Indonesia. Meanwhile, the biomass prediction model used for native tropical lowland trees of Indonesia is limited to only specific locations and focuses on aboveground biomass (AGB). This study aimed to select and evaluate potential native tree species for high biomass and to develop the best allometric model for estimating tree biomass production (AGB, belowground/BGB, and total/TB) in lowland ecosystems in Indonesia. Trees were selected using the following five criteria: nativeness, ecosystem type, morphological appearance, multipropagation ability, and economic value. Biomass content was quantified for 102 sample trees (56 trees aged 4 years and 46 trees aged 8 years), using the destructive method. Effective growth biomass and species ecological data indicated five species as potential trees for land restoration in tropical lowlands of Indonesia: Litsea garciae, Terminalia bellirica, Pterospermum javanicum, Anisoptera marginata, and Cananga odorata. The best allometric model of this study is highly recommended for implementation with native trees of tropical lowlands in Indonesia, especially those in early stages (less than 8 years).

“…The studies investigating the dynamics of carbon stock in post-mining areas in Indonesia have been previously reported by several authors, such as in Kutai Kartangera, East Kalimantan (Yunanto et al 2022) and Kolaka, Southeast Sulawesi (Purnomo et al 2022). In this study, we evaluated the changes in the C content in the soil after the mining and rehabilitation of post-coal mining land in Berau, East Kalimantan.…”

Abstract. Hartati W, Sudarmadji T. 2022. The dynamics of soil carbon in revegetated post-coal mining sites: A case study in Berau, East Kalimantan, Indonesia. Biodiversitas 23: xxxx. Open pit mining practices cause the loss of vegetation cover as well as soil degradation. Post-mining land reclamation and revegetation are therefore enforced to recover the vegetation and soil quality. While several studies have revealed vegetation succession following post-mining revegetation, limited studies have focused on the carbon dynamics of the soil. This study aimed to investigate the dynamics of soil carbon stock due to mining operations and how it changed following revegetation. The research was carried out in the concession area of a coal mining company in Berau, East Kalimantan, which was divided into three sites: Sambarata Mining Operation (SMO) Site, Binungan Mining Operation (BMO) Site, and Lati Mining Operation (LMO) Site. At each site, eight research measurement plots (RMP) were established representing land with varying vegetational conditions, namely original land and post-mined lands with varying revegetation stages from open land to 12-year-old vegetation. The percentage of C content was calculated from 288 disturbed soil samples, while bulk density was analyzed from 144 whole soil samples using the Walkey & Black and gravimetric methods. We found that the C stock at the initial state after the mining operation was very low. Coal mining activities caused a loss of C in soil with an average value of 21.29%, or equal to 5.65 tons/ha. The biggest loss occurred at the SMO site (44.97%, or 13.04 tons/ha), while the smallest loss was found at the LMO site (2.24%, or 0.40 tons/ha). The carbon stock improved after revegetation, particularly in the SMO and LMO sites, and the rate of carbon stock enhancement in the soil differed across sites. The results also showed that soil carbon in the post-mining area of 10-30 cm was greater than that of the 0-10 cm layer. Along with the increasing age of plants, the vertical distribution of C stock shifted from the lower layer to the upper layer.
